I stayed at fabs hostel for 3 days and i can only recommend this hostel. Its very nice and clean. The outside of the hostel is very cozy. And fab will help you with every Problem you have. For all people who werent in bangkok before this is the best place to go, because fab can tell you everything you need to know about bangkok and will show you the best places this city has.
The hostel is near everything that bangkok has, but still in a very silent neighbourhood.
5 of 5 would stay here again.
